Question

I am writing a powershell script that will be used by many. It uses the PSTools executable called “psexec”.

How can I test at the beginning of the script to see if the user has psexec installed and then throw an error if they dont?

Answer 1

You can do something like below:

$psexec = get-command psexec
if($psexec){
    #continue
}

Get-Command will throw exception if the command does not exist.
